Question

Задача No1 Робот вкрайней левой клетке коридора из 15 клеток. Ему надо покрасить клетки коридора в шахматном порядке (через одну), начиная скрайней левой, и остановиться в крайней правой клетке коридора​

Answer 1

Ответ:

for i in range(7):

   fill_cell()

   move_right()

   move_right()

fill_cell()

Объяснение:

используем цикл с параметром (for i in range(7):), т.к. известен размер коридора (15 клеток)

после цикла добавляем закрашивание последней клетки (fill_cell()), т.к. в цикле робот доходит до клетки, но не закрашивает её

Answer 2

Problem Statement

The problem is to move a robot from the leftmost cell of a corridor with 15 cells to the rightmost cell of the corridor. The robot needs to paint the cells of the corridor in a chessboard pattern, alternating between two colors, starting from the leftmost cell and stopping at the rightmost cell.

Solution

To solve this problem, we can use a simple algorithm that moves the robot one cell at a time and alternates between two colors. Here is a step-by-step solution:

1. Initialize the robot's position to the leftmost cell of the corridor. 2. Initialize a variable to keep track of the current color. Let's say we start with color A. 3. Repeat the following steps until the robot reaches the rightmost cell: - Paint the current cell with the current color. - Move the robot one cell to the right. - Switch the current color to the other color (if it was A, switch to B; if it was B, switch to A). 4. Once the robot reaches the rightmost cell, stop.

This algorithm ensures that the robot paints the cells in a chessboard pattern, alternating between two colors, starting from the leftmost cell and stopping at the rightmost cell.

Example

Let's illustrate the solution with an example. Assume that the leftmost cell is labeled as cell 1 and the rightmost cell is labeled as cell 15. We'll use the letters A and B to represent the two colors.

1. Start at cell 1 with color A. 2. Paint cell 1 with color A. 3. Move to cell 2. 4. Switch to color B. 5. Paint cell 2 with color B. 6. Move to cell 3. 7. Switch to color A. 8. Paint cell 3 with color A. 9. Move to cell 4. 10. Switch to color B. 11. Paint cell 4 with color B. 12. Move to cell 5. 13. Switch to color A. 14. Paint cell 5 with color A. 15. Repeat the steps until reaching cell 15.

By following this algorithm, the robot will paint the cells of the corridor in a chessboard pattern, starting from the leftmost cell and stopping at the rightmost cell.

Note: The specific implementation details, such as the programming language or the representation of the corridor, are not provided in the problem statement. The solution described here is a high-level algorithm that can be implemented in any programming language or using any suitable data structure.

Conclusion

In conclusion, the problem is to move a robot from the leftmost cell of a corridor with 15 cells to the rightmost cell, while painting the cells in a chessboard pattern. The solution involves a simple algorithm that alternates between two colors and moves the robot one cell at a time. By following this algorithm, the robot will paint the cells in the desired pattern and reach the rightmost cell.
